Abstract


Large-scale -- even genome-wide -- duplications have repeatedly been invoked as an explanation for major radiations. Teleosts, the most species-rich vertebrate clade, underwent a ``fish-specific genome duplication&#039;&#039; (FSGD) that is shared by most ray-finned fish lineages. We investigate here the <em>Hox</em> complement of the goldeye (<em>Hiodon alosoides</em>), a representative of Osteoglossomorpha, the most basal teleostean clade. An extensive PCR survey reveals that goldeye has at least eight \emph{Hox} clusters, indicating a duplicated genome compared to basal actinopterygians. The possession of duplicated <em>Hox</em> clusters is uncoupled to species richness. The <em>Hox</em> system of the goldeye is substantially different from that of other teleost lineages, having retained several duplicates of <em>Hox</em> genes for which crown teleosts have lost at least one copy. A detailed analysis of the PCR fragments as well as full length sequences of two <em>HoxA13</em> paralogs, and <em>HoxA10</em> and <em>HoxC4</em> genes places the duplication event close in time to the divergence of Osteoglossomorpha and crown teleosts. The data are consistent with --- but do not conclusively prove - that Osteoglossomorpha shares the FSGD.
